A/C and powersteering lines.

[Slide]

I'm getting ready to install dash air A/c and power steering in my 05 Eagle, I am planing to run steel lines the length of the bus with rubber hose at both ends. My question is, what side lines should I run ? I have in mind 3/8 for the high pressure and 1/2 for the return low pressure.Any and all input welcome,thanks.

Remember that the pressure line of the power steering can top out at 2500psi, even higher when cold.  Good Luck, TomC
